1Slacker’s Guide to Thoracic Gross Anatomy Prepared by Mike Ori
2Caveat EmptorAs with all slackers guides, I have omitted, condensed, and misunderstood information so don’t complain if I got something wrong, after all, you’re a slacker.Also, it goes without saying that the faculty has not vetted the information in any way. Always refer to their notes and lectures for the last word.
3CT and SuchYou’re probably best off working on an interactive system tryCPR Radiograph key from Slice-o lecture is important
